A brief review on biocontrol potential and PGPR traits of Streptomyces sp. for the management of plant diseases

Author(s): SB Gowdar, H Deepa and YS Amaresh
Abstract: Streptomyces is the largest genus of Actinobacteria and the type genus of the family Streptomycetaceae. Streptomyces are soil saprophytes and are responsible for earthy odour of freshly ploughed soil due to production of geosmin. Now a days farmers became more and more dependent on agrochemicals but increasing negative effects. So alternative approaches like use of biocontrol agents for management of plant disease is very important. In that Streptomyces is also contributing for plant growth promotion activity and plant disease suppression. Streptomyces also produces some of the secondary metabolites such as indole acetic acids and chitinase. Streptomyces acts as both plant growth promoting rhizobacteria and also plant disease suppressor by various mechanisms like increase in the supply of nutrients such as phosphorus, sulphur, iron, copper, production of IAA, cytokinin and siderophor production; plant growth promoting through multi-dimensional manner by producing plant hormones; controlling fungi and bacterial disease through antibiosis and competition.
